1Impact of body composition on survival and morbidity after liver resection in hepatocellular carcinoma patients显示文摘Background: Hepatocellular carcinoma is the most common innate liver tumor. Due to improved surgical techniques, even extended resections are feasible, and more patients can be treated with curative intent. As the liver is the central metabolic organ, preoperative metabolic assessment is crucial for risk stratification. Sarcopenia, obesity and sarcopenic obesity characterize body composition and metabolic status. Here we present the impact of body composition on survival after liver resection in patients with hepatocellular carcinoma. Methods: A retrospective database analysis of 70 patients who were assigned for liver resection due to hepatocellular carcinoma was conducted. For assessment of sarcopenia and obesity, skeletal muscle surface area was measured at lumbar vertebra 3 level(L3) in preoperative four-phase contrast enhanced abdominal CT scans, and L3 muscle index and body fat percentage were calculated. Results: Univariate analysis comparing the survival curves using the score test demonstrated superior postoperative overall survival for sarcopenic( P = 0.035) and sarcopenic obese( P = 0.048) patients as well as a trend favoring obese( P = 0.130) subjects. Whereas multivariate analysis could not identify significant difference in postoperative survival regarding sarcopenia, obesity or sarcopenic obesity. Only large tumor size, multifocal disease and male gender were risk factors for long-term survival. Conclusions: Sarcopenia, obesity and sarcopenic obesity are indeed no risk factors for poor postoperative survival in this study. Our data do not support the evaluation of sarcopenia, obesity and sarcopenic obesity before liver resection in hepatocellular carcinoma patients.Andreas Kroh Diane Uschner Toine Lodewick Roman M Eickhoff Wenzel Sch?ning Florian T Ulmer Ulf P Neumann Marcel Binneb?sel 2019Hepatobiliary & Pancreatic Diseases International2019,18,1:5

3Differences in individual susceptibility affect the development of trigeminal neuralgia显示文摘Trigeminal neuralgia is a syndrome due to dysfunctional hyperactivity of the trigeminal nerve,and is characterized by a sudden,usually unilateral,recurrent lancinating pain arising from one or more divisions of the nerve.The most accepted pathogenetic mechanism for trigeminal neuralgia is compression of the nerve at its dorsal root entry zone or in its distal course.In this paper,we report four cases with trigeminal neuralgia due to an unknown mechanism after an intracranial intervention.The onset of trigeminal neuralgia after surgical interventions that are unrelated to the trigeminal nerve suggests that in patients with greater individual susceptibility,nerve contact with the vascular structure due to postoperative pressure and changes in cerebrospinal fluid flow may cause the onset of pain.Yusuf Kurtulus Duransoy Mesut Mete Emrah Akay Mehmet Seluki 2013Neural Regeneration Research2013,8,14:3
4Laboratory evaluation in rheumatic diseases显示文摘Autoantibodies can help clinicians to allow early detection of autoimmune diseases and their clinical manifestations, to determine effective monitoring of prognosis and the treatment response. From this point, they have a high impact in rheumatic disease management. When usedcarefully they allow rapid diagnosis and appropriate treatment. However, as they may be present in healthy population they may cause confusion for interpreting the situation. False positive test results may lead to wrong treatment and unnecessary anxiety for patients. Autoantibody positivity alone does not make a diagnosis. Similarly, the absence of autoantibodies alone does not exclude diagnosis. The success of the test is closely related to sensitivity, specificity and likelihood ratios. So, interpretation of these is very important for a proper laboratory evaluation. In conclusion, in spite of the remarkable advances in science and technology, a deeply investigated anamnesis and comprehensive physical examination still continue to be the best diagnostic method. The most correct approach is that clinicians apply laboratory tests to confirm or exclude preliminary diagnosis based on anamnesis and physical examination. This review will discuss these issues.Murat Birtane Sel?uk Yavuz Nurettin Ta?tekin 2017World Journal of Methodology2017,7,1:3
5Mesenchymal stem cell therapy in patients with small bowel transplantation:Single center experience显示文摘AIM:To study the effects of mesenchymal stem cell(MSC) therapy on the prevention of acute rejection and graft vs host disease following small bowel transplantation.METHODS: In our transplantation center, 6 isolated intestinal transplants have been performed with MSC therapy since 2009. The primary reasons for transplants were short gut syndrome caused by surgical intestine resection for superior mesenteric artery thrombosis(n = 4), Crohn's disease(n = 1) and intestinal aganglionosis(n = 1). Two of the patients were children. At the time of reperfusion, the first dose of MSCs cultured from the patient's bone marrow was passedinto the transplanted intestinal artery at a dose of 1000000 cells/kg. The second and third doses of MSCs were given directly into the mesenteric artery through the arterial anastomosis using an angiography catheter on day 15 and 30 post-transplant.RESULTS: The median follow-up for these patients was 10.6 mo(min: 2 mo-max: 30 mo). Three of the patients developed severe acute rejection. One of these patients did not respond to bolus steroid therapy. Although the other two patients did respond to antirejection treatment, they developed severe fungal and bacterial infections. All of these patients died in the 2nd and 3rd months post-transplant due to sepsis. The remaining patients who did not have acute rejection had good quality of life with no complications observed during the follow-up period. In addition, their intestinal grafts were functioning properly in the 13th, 25th and 30th month post-transplant. The patients who survived did not encounter any problems related to MSC transplantation.CONCLUSION: Although this is a small case series and not a randomized study, it is our opinion that small bowel transplantation is an effective treatment for intestinal failure, and MSC therapy may help to prevent acute rejection and graft vs host disease following intestinal transplantation.Sait Murat Do?an Sel?uk K?l?n?

6The predictive value of triglyceride-glucose index for in-hospital and one-year mortality in elderly non-diabetic patients with ST-segment elevation myocardial infarction显示文摘BACKGROUND Triglyceride-glucose(TyG)index,a reliable marker of insulin resistance,was associated with cardiovascular morbidity and mortality.This study aimed to evaluate the predictive value of TyG index for mortality in elderly non-diabetic pa-tients with ST-segment elevation myocardial infarction(STEMI).METHODS In total,430 non-diabetic patients aged over 65 years with STEMI were consecutively included.The TyG index was calculated by using the following formula:TyG index=ln(fasting triglyceride×fasting glucose/2).The 5-item modified frailty index score was utilized to determine comorbidities.Patients were divided into three groups based on TyG index tertiles.RESULTS Patients included into high TyG index tertile were male and had higher body mass index,glucose,triglyceride,low-density lipoprotein cholesterol,5-item modified frailty index and GRACE risk score;and had low systolic blood pressure,estim-ated glomerular filtration rate and left ventricular ejection fraction.A one-unit increase in TyG index was associated with 3.03 ex-tra cases per 1000 person-day for in-hospital mortality and 0.29 extra cases per 1000 person-day for long-term mortality.There was a non-linear relationship between TyG index and the risk of mortality with an increased risk above 8.5 for TyG index.Kaplan-Meier survival curves revealed that patients in high TyG index tertile had higher in-hospital and long-term mortality rates than those in low TyG index tertile.CONCLUSIONS This was the first study to demonstrate that the TyG index could predict in-hospital and long-term mortality in elderly non-diabetic STEMI patients.FaysalŞaylık TufanÇınar Murat Selçuk İbrahim Halil Tanboğa 2022Journal of Geriatric Cardiology2022,19,8:3
7Investor sentiments and stock marketsduring the COVID-19 pandemic显示文摘This study examines the relationship between positive and negative investor sentiments and stock market returns and volatility in Group of 20 countries using variousmethods, including panel regression with fixed effects, panel quantile regressions, apanel vector autoregression (PVAR) model, and country-specific regressions. We proxyfor negative and positive investor sentiments using the Google Search Volume Indexfor terms related to the coronavirus disease (COVID-19) and COVID-19 vaccine, respectively. Using weekly data from March 2020 to May 2021, we document significantrelationships between positive and negative investor sentiments and stock marketreturns and volatility. Specifically, an increase in positive investor sentiment leads toan increase in stock returns while negative investor sentiment decreases stock returnsat lower quantiles. The effect of investor sentiment on volatility is consistent acrossthe distribution: negative sentiment increases volatility, whereas positive sentimentreduces volatility. These results are robust as they are corroborated by Granger causalitytests and a PVAR model. The findings may have portfolio implications as they indicatethat proxies for positive and negative investor sentiments seem to be good predictorsof stock returns and volatility during the pandemic.Emre Cevik Buket Kirci Altinkeski Emrah Ismail Cevik Sel Dibooglu 2022Financial Innovation2022,8,1:2
